Figure 9-37 OSI/IP Scenario 8: OSI OSS, OSI DCN, ONS GNE, OSI DCC, and Other Vender NEs
1 The ONS NEs are managed by CTC/CTM only (TL1/FTP is not used).
2 The OSI OSS manages other vendor NEs only.
3 CTC/CTM communicates with the ONS 15600 over an IP-over-CLNS tunnel between the
ONS 15600 NE and the external router. A static route is needed on the GNE.
4 The ONS 15600 GNE routes OSI traffic to other vendor NEs. No IP-over-CLNS tunnel is
needed.
